I'm planning my upgrades of the off-season, and my 1st to-do is change gearing, since mine is stock (14/39). This is for an 06 749 biposto.
1st question - I've read 14 is the lowest you wanna go in the front - is that true?
There are a lot of short tracks in the midwest (blackhawk, putnam, etc) that have pretty short straights, so my current gearing is awful. Fiddling with www.gearingcommander.com, I noticed that going to +3 rear at 11k rpm will hit roughly 153 mph - probably faster than you'll need at blackhawk. Are there any negatives to going +4 in the rear?
Also, chain links - going form 96 links to 97 significantly improves the "sprocket and chain wear" on gearingcommander. is there any issues with this?
Last one - 525 or 520?
This is for a track-only bike, no street miles at all.
Thanks!
